7 WRINGER Application filed March'IB, 1931. Serial No. 523,739.

My invention relates to wringer devices used or useful for mopping offloors and the like.

Objects of my invention are:

To provide asimple, convenient, and easily operable wringerdeviceformopping;

To provide compartmentstherein for: clean and unclean water orsoapy .orotherwise prepared fluid adapted'to be used in mopping;

To provide thereon abrake means to retain the device in position while amop is being wrung out or while the device isintended to stand still onan inclined floor;

' To provide thereon a wringer means for each compartment requiring onlyone movement of a handle to position the wringing rollers for mopwringing over either one of the compartments; 1 v I To provide thereon amop feeding means which also tends to increase the wringing out of themop; I

To provide thereon a discharge-control N means having one drain valveconnected to all compartments and having one discharge outlet so thatthe contents of any one orof all of the compartments can selectively bedischarged, wholly or in part, while the device remains in one position;

To provide thereon a means whereby the movable roller is automaticallyheld in wringing relation with the companion roller after the samehasbeen moved into that relation;

To provide thereon an adjusting means to vary the tension of the springswhich act on the rollers over the compartments.

Other objects will be pointed out herein below or will become obvious orapparent or N will suggest themselves upon an inspection of theaccompanying drawings and this specification. v w

I attain my objects by the mechanism illustrated in the accompanyingdrawings, in

which: Fig. 1 is a plan view of a wringer device for mopping embodyingmy invention.

Fig; 2 is a side view of the device of Fig. 1.

Fig. 8 is a transverse section takenon the line 3-3 in Fig. 2.

Fig. 4 is a transverse section of the drivin roller taken on the line Hin Fig. 3.

imilar reference characters refer tosimilar parts throughout the views.

The tank, as shown, i divided into two compartments A and B, and hasfour wheels G on the bottom thereof. All of the wheels may be mounted oncastors for easy steering of .the device but it is preferred that onlythe two wheels on one end be mounted on castors 150 so that one brakewill hold the device against lateral and circular movement.

. The castors 10 are mounted on thebottom of the tank at one end thereofand carry the steering wheels and usual brackets and wheels journaledtherein, well known in the art, are mounted on. the bottomjofthe tank atthe other end thereof.

The valve D, as shown, is a three way valve having the inlet 11 with thepipe connection 12 leading to the compartmentA and also having the inlet13 with the pipe-connection l l leading to the compartment:B and alsohaving the outlet 15. Upon rotation of the handwheel 16, in respectivedirections, either the inlet 11 or the'inlet 18, or both, may beconnected to or with the outlet15 so that the device may be moved into asuitable position therein the outlet is disposedflover a dischargereceptacle and the. contents of either one or of both of thecompartments can be discharged with one positioning of the device.

The bracket 17 is mounted on one end of the device and carries the lever18 pivoted thereon by means of the pivotpin 19. The link 20 is pivotedonto the lever at 21' and extends downwardly. The brake shoe 22, adaptedto contact the floor'upon which the device rests, is mounted on the stem23 which is guided on the bracket 24: and which is pivotally connectedto the link at 25. V V I The pivots 19 and 21 are arranged so that thesame are beyond dead centers-when the lever contacts the bottom of theslot in the bracket 17 and thereby lock the brake when it is applied.The drawing shows the lever moved far enoughto contact the brake shoe onthe floor; an additional downward movement of the lever moves the pivot21 past the dead center with the pivot 19 and thereby tends to raise thedevice and puts the weight of one end of the device onto the brake foreffective braking thereof and at the same time locks the brake.

The lever 18 is bent to remove the free end thereof from the tank whenthe brake is applied so that the free end can be taken hold of torelease the brake and to extend the free end thereof over the top of thetank when the brake is released so that the lever remains in brakereleasing position due to gravity thereof. 7

. The brake shoe may be madeof rubber or wood or other material to besomewhat resilient and having the property of frictional engagementswith floors or may be made of metal or other material with a frictionproducing lining on the bottom thereof.

The rollers E and F are journaled respec: tively in the two bearingblocks 26 and 26a which are slidable in and guided by the frame bars 27and 28 extending along the top of the tank at each side thereof and aretied together by the frame parts 29 extendingtransversely of the tank ateach end thereof.

One end of each of the springs 30 abut the respective bearing blocks andthe other ends thereof abut the respective washers 31; The adjustingscrews 32 abut the respective ones of'said bearing blocks and arethreaded into the spacers 33 located atthe end of the bars 27 and 28. l

The springs provide lateral resiliency for the rollers E and F so thatthe same can move laterally to some extent when a mop or other implementof various thicknesses is being wrung out and always tend to keep therollers against the mop.

The spring adjustment provides means whereby the mop wringing pressurecan be varied to suit different thicknesses of mops or to wring mopsmore or less dry.

The roller G is journaled in the two bearing blocks 34 by means of theshaft 35 which carries on one or both ends thereof a crank 36 forrotation of the shaft and the roller thereon.

The bearing blocks 34 can slide longitudinally of the bars 27 and 28 andare guided thereby and between them.

The roller G is movable into mop wringing relation with the rollers Eand F or to any position between the same by means of the belowdescribed toggle mechanism.

The brackets 37 are secured to the respective bars 27 and each has thepivot pin 88.

The levers 39 have one of the ends thereof pivoted onto the respectivepivot pins 38. The round bar 40 connects the other ends of the levers 39and at the same time serves as a handle to propel the device as well asto steer the same.

The links 41 have one of theends thereof the corrugations 43 to moreeffectively take hold of the mop as the same feeds through the rollersand at the same time squeezes the mop more effectively as the sides ofthe corrugations engage the same.

As to operation of the device, starting from the position of the partsor elements as shown and described: j

When the parts or. elements are in the positions shown in full linesin-Figs. 1 and 2, the handle40 is outward of. one end of the devicewhere it'can be taken hold of conveniently for propelling and steeringthe device. In this position, the links 41 are substantially horizontal,sufiiciently so to prevent the roller G from backing away from theroller E in themanner of toggle mechanisms when a mop is passing throughthe rollers E and G and thereby provides an effective lock for theroller G against reve'rselateral movement thereof.

Upon holding the end of a mop into the junction of the rollersE and Gand a rotative movement of the driving roller G by means of the crank36, the mop will be fed in between the rollers E and G and is wrung outover the compartment B while it is so being fedv as is well known. Thesprings 30 allowing; for unequalities and spreading of the roller E.

Upon movement of the handle 40 arcuately upwardly, the toggle mechanismmoves the roller G away from the roller E as indicated in dot and dashlines in Fig. 2. Upon continuation of this arcuate movement inwardly ofthe device, the roller G is brought into wringing relation with theroller F as is also indicated in dot and dash lines in Fig. 2.

A rotative movement of the crank will wring out a mop over thecompartment A in the manner just described.

A reverse movement of the handle 40 brings tlfie parts back to the fullline positions there- 0 Changes and modifications can be made in thestructure and arrangement of the parts or elements shown and describedwithin the spirit and intent of my invention and of the appended claims;therefore, without limiting myselfto the precise structure andarrangement of the parts or elements as shown and described i I claim:
